scientific study of human populations
a periodic and official count of a country's population
number of individuals per unit area
Arithmetic population density
the population of a country or region expressed as an average per unit area. The figure is derived by dividing the population of the areal unit by the number of square kilometers or miles that make up the unit
Physiologic population density
The number of people per unit area of arable land.
structure of a population in terms of age, sex and other properties, education
displays the percentage or actual amount of a population broken down by gender and age
Crude birth rate (CBR)
the number of live births per 1000 people
Crude death rate (CDR)
the number of deaths per 1000 people
A figure that describes the number of babies that die within the first year of their lives in a given population
Total fertility rate (TFR)
a measure of the reproductive status of a population
Demographic transition (cycle)
model used to show the stages of how a country develops, based on birth/death rates (four stages)
the time required for a population to double in size
growth of a population that multiplies by a constant factor at constant time intervals
Growth in which a quantity increases by some fixed amount during each unit of time.
Crude death rate subtracted from crude birthrate
the rapid growth of the world's human population during the past century
Stationary population level (SPL)
the level at which a national population ceases to grow.
the EXACT way or direction to get to something (north,south,east,west)
The regional position or situation of a place relative to the position of other places.
The distance that can be measured with a standard unit length, such as a mile or kilometer.
distance measured, not in linear terms such as miles or kilometers, but in terms such as cost and time.
negative conditions and perceptions that induce people to leave their adobe and migrate to a new location
a factor that draws or attracts people to another location
Activity (action) space
the space within which daily activity occurs.
movement that has a closed route and is repeated annually or seasonally
movement among a definite set of places
Movements that are taken based on a seasonal basis
a movement from one country or region to another
movement of individuals out of a population
human migration flows in which the movers have not choice but to relocate
Permanent movement undertaken by choice.
Permanent movement within a particular country.
migration across an international border
Permanent movement from one region of a country to another.
migration to a distant destination that occurs in stages, for example, from farm to nearby village and later to a town and city
the return of migrants to the regions from which they earlier emigrated
The presence of a nearer opportunity that greatly diminishes the attractiveness of sites farther away.
The diminishing in importance and eventual disappearance of a phenomenon with increasing distance from its origin.
an exile who flees for safety
refugees encamped in a host country or host region while waiting for resettlement
Refugees who have been substantially integrated into the host country or host region and who are thus seen as long-term visitors.
refugees who have crossed 1 or more international boundaries during their dislocation
laws and regulations of a state designed specifically to control immigration into the state
Eugenic population policy
government policy designed to favor one race over another
Expansive population policy
government policy that encourages large families and raises the rate of population growth
Restrictive population policy
Government policy designed to reduce the rate of natural increase.
Negative population growth
The actual decline in population due to less than replacement births or extensive diseases. When the death rate exceeds the birth rate.
